Bohai drilling first logging company completes the three dimensional horizontal well logging task
China Petroleum Network News reporter learned in October 10th, Bohai drilling first logging company Changqing project department L10421 team to record the first three-dimensional horizontal well Su 76-11-9H well smooth delivery. The qualified rate of mud logging data is 100%, the oil and gas show rate is 100%, the accuracy rate of card layer is 100%, the time prediction rate of field operation team is 100%, and the coincidence rate of section is 94.6%.
Since this well is a three-dimensional horizontal well, it differs from the conventional horizontal well in drilling methods. The effect of high build-up rate, dogleg degree and other factors, to three levels of downhole drilling difficult or Nii eyes, bring the risk to the late trajectory of horizontal wells and underground safety control. Drilling tool structure and well trajectory are complex, which makes it difficult to implement and restore oil and gas display. Drilling can not accurately reflect the lithology and physical properties of the formation, which brings great difficulties to field logging.
The company was fully prepared to ensure accurate sampling in the process of drilling cuttings; timely 3D horizontal well vertical depth map, drilling trace map, so that accurate stratigraphic horizon and accurate, timely and accurate prediction of abnormal, ensure the safety of underground construction, completed the task well logging.
