FUZZY COMPREHENSIVE EVALUATION METHOD TO CHOOSE THE CANDIDATE WELLS FOR FRACTURING

To obtain good fracturing and acidizing treatment,it is important to select appropriate working wells. There are many factors that affect choosing the right working wells. The relation between them is very complicated and they possess definite fuzziness. The traditional methods of choosing the wells are based on experience,which possess definite subjectivity. With the aid of modern mathematical means:fuzzy mathematics and level analysis principle of systematic engineering, multi stage comprehensive evaluation measure is formed for choosing the right wells of fracturing and acidizing. The result of this method is accurate and reliable and is accord with the practical effects. This method is simple and convenient. So it has a certain practical value.
