摘要： A method of installing a pressure transducer in a borehole to measure the fluid pressure 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.

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 bit (6) is equipped with one or more fluid jets (7) that are activated during a portion of the rotational movement of the drill bit (6). A processor (41) located with other down-hole sensors (33-38), is programmed with parameters defining the desired path of the borehole (8). The sensors (33-38) determine the actual spatial location of the drill bit (6) and provide the processor (41) with corresponding information. The processor (41) compares the actual drilling path to the desired path, and if a correction is required, a switching module (3) allows a pressurized drill fluid to be sequentially switched to selected jets (7) during rotation of the drill bit (6) to thereby erode the formation in a direction toward the desired path. With this arrangement, the problems of directional control by surface-located equipment are overcome.

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 method of degassing a coal seam by djrectionally drilling a borehole in a rock formation that is adjacent the coal seam, or between two different coal seams. The borehole is then pressurised to fracture the adjacent coal seam(s) to enhance the permeability thereof and allow fluids to flow from the coal seam to the borehole and be extracted from the coal seam.

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 dump 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 arc 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.
摘要翻译：使用井下工具通过电缆取芯系统的钻柱进行钻杆测试，所述井下工具包括测试区域封隔器，阀封隔器，具有倾泄阀和主阀的闩锁组件，所有这些都通过电缆在通信电缆和充气管，以安置在岩心筒中。气体压力将钻柱中的液位降低到合适的测试水平，通过给封隔器系统充气以将阀封隔器密封在钻柱内并使用单或双封隔器隔离测试区域来保持合适的测试水平。压缩气体从钻柱中释放，使其不受压并且其中的液位降低。可以通过升高钻柱以引起向内流体流动来打开阀，并且在流动期之后通过降低钻柱来关闭阀。然后进行压力恢复过程，其中压力由井下传感器测量并通过通信电缆传输至地面。在放气之前，钻柱充满液体，通过拉动电缆线以打开井下工具中的卸料阀并释放封隔器充气压力来释放充气压力。在放气期之后，钢丝绳被进一步拉动，由此释放闩锁组件并允许工具通过钢丝绳与充气管和通信电缆一起被拉到地面。
