2、如下，第一章內(nèi)容），利用C和Python編寫(xiě)了一個(gè)可以批量處理的小軟件。第1章WIS測(cè)井?dāng)?shù)據(jù)文件格式WellBase平臺(tái)底層數(shù)據(jù)文件使用WIS格式，WIS文件分為文件頭、對(duì)象入口記錄和對(duì)象數(shù)據(jù)三部分。數(shù)據(jù)存放以塊為單位。WIS文件能存放三種類型的對(duì)象，根據(jù)對(duì)象的類型分為通道對(duì)象、表對(duì)象和流對(duì)象。通道對(duì)象一般用來(lái)存放采集數(shù)據(jù)和處理結(jié)果（如測(cè)井曲線），表對(duì)象用來(lái)存放二維表數(shù)據(jù)（如解釋結(jié)論），流對(duì)象用來(lái)存放二進(jìn)制數(shù)據(jù)塊（如解釋參數(shù)，用戶數(shù)據(jù)）。1.1.1 WIS文件結(jié)構(gòu)文件標(biāo)識(shí)WIS文件標(biāo)識(shí)從文件偏移零開(kāi)始，為10個(gè)字節(jié)的字符。當(dāng)前版本的標(biāo)識(shí)為WIS1.0。1.1.2 文件頭結(jié)構(gòu)頭結(jié)構(gòu)緊接文件標(biāo)識(shí)。
