摘要： A gas analysis system for determining the gas content of subterranean strata. A boring operation is commenced to form a borehole into or through a subterranean formation, such as a coal or shale formation to determine the gas content thereof. The drill fluid, cuttings and any desorbed gas is carried from the downhole location to surface analysing equipment in a closed system, so that the desorbed gases are not exposed to the air. The drill stem is capped or sealed at the surface, as well as the wellbore annulus to effectively seal the drill liquid, cuttings and desorbed gasses. The drill fluid, cuttings and desorbed gasses from the formation are coupled from the wellhead apparatus to the gas processing equipment via a closed system so that the constituents and volume of the gas can be determined.

摘要： A drill stem test conducted through the drill string of a wireline coring system using a downhole tool comprising test zone packers, a valve packer, a latching assembly with a clump valve and main valve, all of which are conveyed on the wireline with a communications cable and inflation tube, to seat in the core barrel. Gas pressure drives the liquid level in the drill string down to a suitable test level which is retained by inflating the packer system to seal a valve packer within the drill string, and isolating the test zone using single or dual packers. The compressed gas is relieved from the drill string leaving it unpressurised and with a depressed liquid level therein. A valve can be opened by raising the drill string to induce inward fluid flow, and after a flow period the valve is shut by lowering the drill string. A pressure recovery process then takes place, in which the pressures are measured by downhole transducers and transmitted to surface via the communications cable. Prior to deflation, the drill string is filled with a liquid and the inflation pressure is relieved by pulling on the wireline to open the dump valve in the downhole tool and relieve packer inflation pressure. After a deflation period the wireline is pulled further, thereby releasing the latch assembly and allowing the tool to be pulled to the surface by the wireline, together with the inflation tube and communications cable.

摘要： A method and apparatus for cementing a zone of borehole casing using an external casing packer (ECP). The method involves sealing the base of the ECP with a ball dropped in a seat, and then pressurising the casing to inflate an elastomeric packer sleeve through a one-way valve. When a design differential pressure is reached across the casing and elastomeric sleeve, a grout valve in the upper part of the packer opens to limit the sleeve inflation pressure and to provide a one-way valve through which cement grout passes to permit grouting of the annulus between the casing and the borehole.

摘要： The invention is a separator designed to separate an incoming stream of liquid, gas, and some particulate matter into a separate gas stream, and a separate liquid stream containing the particulate matter. This is achieved through cyclonic action and the use of a float to operate internal valves within the cyclone. The float is mounted on a shaft which is rotated by the motion of the incoming fluid stream and this motion is used to agitate the solids in the liquid so as to prevent the outlet port from becoming jammed. The outlet port also has an auger contained therein that removes particulate matter.

摘要： A pumping system in which a pump (5) is controlled by a programmed controller (22) in response to input signals from an inlet pressure transducer (3) and an outlet pressure transducer (15) and in certain circumstances inputs from various flow sensors (4,19). The controller (22) can be programmed to allow the pump (5) to prematurely operate before an outlet pressure reaches a low pressure threshold, when usage of the liquid is high. The controller (22) can be programmed to detect a lack of prime of the pump (5), to restore prime once the pump (5) has lost prime, and to prevent successive on/off pump cycles when the outlet flow is continuous and at a moderate or low level.

摘要： A steering collar for deflecting a drill string in a borehole to cause the borehole to be drilled in a different direction. The steering collar surrounds a hollow drive shaft which is driven by the drill string. During normal drilling operations, the steering collar does not rotate with the drive shaft. The steering collar has three sets of pistons operated by the pressure of the drilling fluid, one set of which is pressure relieved. Drill fluid that is pumped down the drill string flows into the hollow drive shaft and through ports to activate the pistons which thereby force corresponding pads outwardly into contact with the sidewall of the borehole. Since the one set of pistons is pressure relieved, it does not force its pad against the borehole sidewall with as much pressure as the other two sets of pistons force their pads against the sidewall of the borehole. Accordingly, the steering collar is deflected laterally in the borehole so that the drill bit is also steered laterally to cause drilling in a different direction. In order to reorient the steering collar in the borehole, the steering collar can be locked to the drive shaft so that when the drill string is rotated, the steering collar is also rotated so that it is moved to a new angular position in the borehole.

摘要： A method of installing a pressure transducer in a borehole to measure the fluid prepare of a geological formation. The pressure transducer is installed into the borehole at a desired depth, and then the borehole is filled with a cement grout. The fluid connection between the pressure transducer and the formation is opened by pumping a fluid through tubing to displace the cement grout. A process of hydrofracture can be employed to provide a communication path of fluid between the formation and the pressure transducer surrounded by the fractured grout. In one embodiment of the invention, a pressure transducer is cemented into the borehole along with a check and pressure relief valve. In another embodiment, the pressure transducer is installed in the tubing at a subsequent stage.
