Technical Field
The utility model relates to a connect to get detritus and carry out device of screening and straining in being arranged in oil and gas exploration belongs to detritus screening and straining technical field.
Background
In the process of petroleum and gas exploration and drilling, rock fragments which are drilled by a drill bit at the bottom of a well are called rock debris and are continuously returned to the ground along with the circulation of drilling fluid. The rock debris is an intuitive material for timely knowing the lithology of the stratum and the hydrocarbon reservoir. Sampling at certain depth intervals, and depth correction according to the late arrival time of the rock debris. Selecting the mixed samples obtained each time, removing collapsed rock masses, performing geological observation, description and name assignment under naked eyes or a microscope, respectively calculating the mass or volume percentage of each rock fragment sample, determining the rock category of the sampling depth, and making an underground rock fragment stratigraphic profile map by matching with other data. The prerequisite basis of this work is the rock debris fishing, namely must accurately fish the rock debris according to the sampling interval and the delay time. In the debris fishing work, every well must be unified and drag for a kind position, and the sample usually has two places: firstly, a baffle is arranged in the overhead tank for sampling; and the other is added with a sampler for sampling before the vibrating screen. Under the condition of spraying and drilling, a sampling basket is arranged at a spraying pipe opening of the stirrer for sampling; the well leakage is serious, when the well is in or out, the fishing cup is arranged above the drill bit for sampling, and nevertheless, the sampling is carried out at the vibrating screen under the normal operation mode.
In the field construction of oil and gas exploration, a sampling tool for receiving rock debris is a rock debris basin which is a common metal basin and is of a rectangular or circular structure, the rectangular rock debris basin is generally a strip basin with the length of 400mm, the width of 200mm and the height of 180mm, and the circular rock debris basin is generally a conical basin with the upper opening diameter of 350mm, the lower opening diameter of 250mm and the height of 150 mm.
After the rock debris taken in the rock debris basin is full, a part of the rock debris needs to be manually removed, and then the rock debris is continuously connected, otherwise, the continuity and authenticity of the rock debris cannot be guaranteed, and discontinuous manual operation cannot guarantee that the full rock debris can be immediately cut and removed. Therefore, how to ensure the accuracy of the rock debris receiving is correct, the rock debris basin tool needs to be innovated, practical and redesigned.
The detritus basin is placed before the shale shaker, in view of the requirement of detritus butt joint continuity of getting and authenticity, need adopt dichotomy or quartering method to carry out the manual work when the detritus of detritus basin is full and cut apart and get rid of the detritus in the basin, stirs the detritus in the remaining basin again and mixes, otherwise the detritus will be followed the basin top and spilled over to the grit chamber to cause the detritus degree of depth to accurately playback.
However, manual cutting of rock debris has several problems:
(1) the timeliness cannot be ensured, and the rock debris receiving quality is influenced;
(2) the labor intensity of the operation is increased, and the operation efficiency is reduced;
(3) the quality of rock debris receiving is influenced due to the existence of artificial judgment errors;
(4) the method has the advantages that the operation arbitrariness exists, and the authenticity of the rock debris stratum representation cannot be guaranteed;
(5) drilling fluid can overflow along with residual drilling fluid when the rock debris basin is full, so that the normal drilling depth can not be reset through the rock debris;
(6) the ordinary rock debris basin can not quantitatively contain rock debris, and the manual cutting and stripping can cause that the quantity of the rock debris can not meet the requirement, so that the lithology of the formation being drilled can not be judged;
(7) the ordinary debris basin is a simple and crude operation tool and is not beneficial to the standardized construction of field production operation.
Because the manual cutting of the rock debris is a non-instant discontinuous operation, the continuity is lacked, the continuity of the rock debris taking is affected due to untimely control, the authenticity reflection of the rock debris on the stratum is reduced, and the problem to be solved urgently is solved, so that an automatic rock debris cutting and taking device is urgently needed on site.
