Method used for simultaneously integrating WITS data and WITSML data on drilling completion site

The invention discloses a method used for simultaneously integrating WITS (Wellsite Information Transfer Standard) data and WITSML (Wellsite Information Transfer Standard Markup Language) data on a drilling completion site. The method comprises the steps of 1, acquiring a WITS data source in two modes of socket communication and serial communication; acquiring a WITSML data source in an XML stream mode by adopting a SOAP protocol; 2, storing tables of WITSML standard data, taking various objects according to WITSML standards as main tables and object nodes as fields, establishing sub-tables by recursion of sub-nodes of the objects, and establishing database tables by a tree structure to store the data; adding a data table name field, corresponding to a WITS data table name, to a Log object table in a WITSML, adding a field name, corresponding to the Log object data table, to a Log object sub-node table LogCurveinfo, and enabling the WITS and the WITSML to establish a corresponding relationship; and 3, organizing data in a well database into WITSML data streams according to WITSML objects, seamlessly synchronizing the data of the wellsite database to a base server in a unified WTISML standard format, and sharing the data to service providers and users.
