摘要： Friction reducing coatings are made by adding water to a particulate hydratable polymer material having a weight average molecular weight of at least 200,000. A preferred polymer material is a mixture of sodium carboxymethylcellulose and a copolymer of acrylamide and vinylpyridine. The friction reducing coating may be applied to a surface by distributing the particulate polymer material over the surface to form a thin layer which is then wet with water or by applying a water solution of the polymer material to the surface, or by applying a slurry of the polymer material over the surface and wetting the film formed by evaporation from the slurry. The slurry of polymer material may comprise a mixture of hydratable polymer material, a gelling agent, a dispensing agent such as methanol, and a plasticizer, such as glycerol. After applying the slurry to the surface, water is added when the alcohol suspending agent has evaporated.

摘要： Subsurface formations are fractured by a process wherein a first path of flow of a fracturing fluid is established from a pump through a flow control-hammer valve, and a second path of flow is established to the formation to be fractured from a point between the pump and the valve, the pressure of the fluid against the formation from the second path of flow being controlled at a predetermined level, preferably slightly less than the formation fracture pressure, by controlling the fluid flow through the valve in the first path of flow. Next, the flow through the valve is instantaneously terminated to cause a pressure pulse to be transmitted through the second path of flow and against the formation and to cause fracturing thereof. In one embodiment, a rarefaction pulse is transmitted down the second path of flow a spaced distance behind the pressure pulse to cause a decay of the pressure pulse after it has reflected from the formation and before it radiates up the well casing and damages the system.

摘要： A drilling fluid for oil and gas wells which can be converted to a cementitious material suitable in well-cementing operations. The preferred drilling fluid has a water base and contains pozzolan and sufficient colloidal clay to form a thin but effective filter cake on the walls of the borehole during the drilling operation. When desired, an alkaline earth hydroxide, such as calcium hydroxide, is introduced into the drilling fluid to form a cementitious material for use in the borehole, for example, for cementing the casing in the borehole.

摘要： The specification discloses a technique for transmitting randomized pulses generated by a downhole well logging device through a cable to an uphole station. Circuitry is provided within the logging device to receive the randomized pulses. A clock generates a clock signal having a periodic clock frequency. A gate is connected to the output of the clock for selectively gating the clock signal. Circuitry is responsive to the reception of the randomized pulses for operating the gate for a prescribed interval to delete predetermined portions of the clock signal. The output of the gate is divided to generate a series of pulses having periods representative of the reception of the randomized pulses. The series of pulses is transmitted through the cable to the uphole station. Circuitry located at the uphole station utilizes phase lock loop circuitry to reconstruct representations of the randomized pulses in response to the series of pulses.

摘要： A conduit is provided for use in fluid-conducting systems which are subjected to pressure surges and includes an inner conduit for carrying fluid which is surrounded by a body of resilient material adapted to absorb undulations of the inner conduit in response to pressure surges of the fluid. In one embodiment the inner conduit is an expandable conduit and the resilient body is contained within a reinforcing member. In this embodiment, the inner conduit expands in response to pressure surges and thereby functions as an accumulator, so as to prevent damage to equipment in the system, such as pressure gauges, piping, and conduits, or for example, to even out the flow discharge from a positive displacement pump for the fluid.
