摘要： Apparatus and methods are provided for measuring a parameter of a hydrocarbon-bearing well fluid sample while the sample is still in place in the well and at downhole pressure and temperature conditions. A tool is lowered into the well to a downhole location. A well fluid sample is trapped in the tool at the downhole location. While the tool remains within the well, the volume of the well fluid sample is expanded while repeatedly measuring the pressure of the trapped well fluid sample at different volumes and thereby generating pressure versus volume data for the trapped well fluid sample. From this data, various parameters such as bubble-point pressure and compressibility of the sample can be readily obtained. The apparatus is suited for drawing and testing multiple samples in succession. After each sample is tested, it is expelled from the tool so that another sample can be taken. The data can be stored for subsequent analysis at the surface or it can be transmitted to the surface for real time analysis.

摘要： A downhole electrical power supply apparatus has a high fluid pressure source zone and a low fluid pressure discharge zone each defined at least partially within the apparatus. A fluid powered engine provides rotational mechanical output and is powered by fluid flowing from the source zone through the engine to the discharge zone. An electrical powered generator converts the rotational mechanical output of the engine into electrical output.

摘要： A downhole shut-in tool includes in one aspect a pilot valve which when opened places a differential pressure across a piston which in turn operably engages a shut-in valve element to close the shut-in tool. An electronic timer assembly and electric drive motor are provided for controlling the action of the pilot valve. The drive motor is controlled by a load sensor which senses that the motor has stalled when an actuator engages a movement limiting abutment. In another aspect a pilot value is provided which can selectively communicate the pressure differential across the piston so as to repeatedly open and close the shut-in valve element. Efficient methods of drawdown and buildup testing using such an automated multiple operating shut-in tool are provided. Associated automated sampling tools are also disclosed.
