The Pretreatment Of Oilfield Perforating Data And The Research Of Algorithm For Cannon Arrangement

Adapt the method of perforation on the oil operation has become the important means of oilfield development. Before the perforation, The Oil field perforation data must be processed. Then we can ensure accurate perforation position. we named it The Pretreatment of Oilfield Perforating data. It included The extraction of oil perforating data、storage、the interpolation、The smoothing of curve and depth correction. So The Pretreatment of Oilfield Perforating is becoming very important. It affects the determination of oil perforating depth Directly. And It affects the accuracy of the Cannon Arrangement. The Pretreatment of Oilfield Perforating data Is the precondition of perforating quality.In this research the Well logging curves are carried on storage and read. Then using the method of five point three times to make the sample data to be smoothing. And we adapt the method of b-spline for approach to the unified of data before adding the casing and after. laying the foundation for depth correction. In order to resolve the optimization of oilfield perforation depth correction demand. According to the related algorithm and peak feature extraction, Perforating curve mathematical model of peak depth correction is established. An new effective method of peak depth correction is put forward in this paper. In this method, the reasonable peak is selected by using the Extreme. and the position of similar curve segment is selected according to The correlation coefficient method.then the best matching peak is secure.then the peak depth correction of logging curves is computed. The results of the experiment show that the method of peak depth correction has realized more better speed and high accuracy, and the match of curve before and after adding tubes. and it provides reliable and accurate data for petroleum reservoir development.Because of the condition in The Research of Algorithm for Cannon Arrangement. In view of the tubing transmission perforating for Cannon Arrangement. we put forward the Optimization of backtracking algorithm. Increasing the terms of pruning, reducing the steps of the backtracking. and we have reduced the amount of calculation greatly.and have increased the thickness of cannon arrangement and improved its speed. In view of the cable transmission perforating for Cannon Arrangement. we put forward the algorithm of partition for Cannon Arrangement. we have saved the time greatly. we have achieved the algorithm.
