Description

A Sand Washing Machine for Oil and Gas Exploration

technical field

The utility model relates to the field of geological logging cuttings cleaning operation in the oil and gas exploration process, in particular to an oil and gas exploration sand washing operation machine.

Background technique

Drilling fluid (called mud in jargon) refers to the fluid medium used in the drilling process. Drilling fluid can be liquid or gas, therefore, drilling fluid should be called drilling fluid exactly. During the drilling process, the circulating flushing medium used in the hole is also called drilling flushing fluid. Drilling fluid can be divided into clear water, mud, clay-free flushing fluid, emulsion, foam and compressed air according to its composition. Clear water is the earliest drilling fluid, it does not need to be treated, it is easy to use, and it is suitable for areas with complete rock formations and sufficient water sources. Mud is a widely used drilling fluid. It is mainly suitable for unstable rock formations with loose walls, developed cracks, easy to collapse and drop blocks, and swelled and spalled when exposed to water. The main functions of drilling fluid are: (1) cleaning the bottom of the well and carrying cuttings; (2) cooling and lubricating the drill bit and drill string; (3) balancing the rock side pressure on the well wall; (4) balancing (controlling) the formation pressure; (5) ) suspending cuttings and weighting agent; (6) sinking and removing sand and cuttings on the ground; (7) effectively transmitting hydraulic power; (8) bearing part of the gravity of the drill pipe and casing; A large amount of information; (10) Hydraulic breaking of rocks.

The work of geological logging is inseparable from the observation and analysis of rock cuttings, which is also an important basis for formation evaluation and oil and gas resource evaluation. The cuttings carried by the drilling fluid from downhole to the ground are all attached to the drilling fluid dirt. To observe and analyze the cuttings, the attached dirt must be cleaned with clean water to restore the natural color of the underground rock. Therefore, cuttings cleaning becomes An important job in the field of geological logging.
